Abstract

The present paper reports the recent composition results obtained by the Pierre Auger Observatory using both hybrid and surface detector data. The reconstruction of the shower longitudinal profile and depth of maximum with the fluorescence detector is described. The measured average depth of maximum and its fluctuations as function of the primary energy is presented. The sensitivity of rise time parameters measured with the ground stations and the obtained composition results are discussed.
